Super Sweet 100 is a hybrid tomato (Solanum lycopersicum × Solanum pimpinellifolium) cultivar that is primarily grown for its high-yielding, small, sweet cherry fruits. The variety was first introduced to the market in the early 1990s by the seed company Botanik International (now part of Johnny's Selected Seeds) and has since become one of the most commercially and home‑garden popular cherry tomato hybrids worldwide.
Botanical and Horticultural Characteristics
- Fruit: Oblong, “cherry‑type” tomatoes averaging 10–15 mm in length; typical weight 10–12 g. The fruits mature to a bright red color and are noted for a high soluble solids content (approximately 6–9 °Brix), which contributes to their characteristic sweetness.
- Plant habit: Indeterminate vine that can reach 150–180 cm (5–6 ft) in height when trellised. The plant produces a prolific number of clusters, often yielding 150–300 g of fruit per plant per week under optimal conditions.
- Leaves and stems: Typical tomato foliage; leaves are compound with a medium serration. Stems are moderately robust but may require staking or cage support in high‑yield situations.
- Maturity: 55–60 days from transplant to first ripe fruit under standard greenhouse or field conditions.
Growth Requirements
- Temperature: Optimal fruit set and development occur between 20 °C and 27 °C (68 °F–81 °F). Temperatures below 10 °C (50 °F) or above 35 °C (95 °F) can reduce set and increase blossom drop.
- Light: Full sun (minimum 6 h of direct sunlight per day) is recommended for maximum sugar accumulation.
- Soil: Well‑drained, loamy soils with a pH of 6.0–6.8; fertility levels comparable to other tomato cultivars (approximately 150 kg N ha⁻¹, 80 kg P₂O₅ ha⁻¹, 200 kg K₂O ha⁻¹).
- Water: Consistent irrigation to maintain soil moisture at 60–80 % of field capacity; excess moisture can promote fruit cracking and disease.
Disease and Pest Resistance
Super Sweet 100 carries resistance genes to several common tomato pathogens, designated in the cultivar’s official registration as follows:
- Fusarium wilt (Fusarium oxysporum f. sp. lycopersici) – race 1
- Verticillium wilt (Verticillium dahliae) – race 1
- Bacterial spot (Xanthomonas perforans) – resistance group R‑1
The hybrid does not possess resistance to late blight (Phytophthora infestans) or tomato yellow leaf curl virus (TYLCV), and standard integrated pest management (IPM) practices are recommended.
Commercial and Home‑Garden Use
Because of its high yield, uniform fruit size, and pronounced sweetness, Super Sweet 100 is extensively used in:
- Fresh‑market sales (e.g., salad mixes, snacking)
- Processing for tomato sauces and salsas where a natural sweetness reduces the need for added sugar
- Controlled‑environment agriculture (greenhouses, high‑tunnel production) where precise climate control enhances flavor
Breeding and Genetic Background
The cultivar is a first‑generation hybrid (F₁) resulting from a cross between a domesticated tomato line and a wild relative, S. pimpinellifolium, selected for fruit size, sugar accumulation, and disease resistance. The exact parental lines are proprietary and not publicly disclosed. As a hybrid, seed saved from the fruit will not reliably reproduce the cultivar’s performance characteristics; growers obtain new seed each season from licensed seed producers.
Regulatory and Trade Information
- Plant Variety Protection (PVP): Super Sweet 100 is protected under the Plant Variety Protection Act in the United States; the protected status expired in 2022, after which the variety entered the public domain for seed production.
- International Naming: The name “Super Sweet 100” is used globally, though some markets list the cultivar under the seed‑company brand (e.g., “Super Sweet 100™”).
